seriously, think about the support calls they have with people's phones being trashed because of a malformed forced upgrade. thats ridiculous. as for it being OTA, when EDGE or something of the like comes out AND when there is more memory (64MB and more), then perhaps that'd be something to think about. right now, even with 32MB of memory, there is not enough to load into memory the upgraded software and then install it (would require no less than 35MB).
In the beginning the Universe was created. This has made a lot of people very angry and is widely regarded as a bad move.
